GAS-STOVE FOR HEATING.

Specification forming part of Letters Patent No. 55,652, dated June 19, 1866.

To all whom it may concern.-

Be it known that I, DAVID GREENE HAS- KINs, of Cambridge, in the county of MiddleseX and State of Massachusetts, have invented a new and useful Improvement in Gas-Stoves; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 represents a front elevation; Fig. 2, a transverse section of Fig. 1.; Fig. 3, a plan view of the hot-air chamber, and Fig. 4 a longitudinal section of a radiating-chamber forming part of the mantel.

Similar letters indicate like parts in the several figures.

The object of my invention is to supply a room or apartment with heated air freed from the disagreeable properties of the consuming gases, and to efi'ect a greater degree of radiation than that produced by the gas-stoves in common use and the invention consists in the combination of an outer casing and inner radiating-chambers supplied with air to be heated from the apartment itself, or by means of apipe leading fromthe outer air, the products of combustion being carried off by means of a separate pipe.

In the drawings, A represents the outer casing, which may be made of any suitable shape. B represents an air-heating compartment in the upper part of the casing, and separated from the lower open compartment, 0, by means ofa partition, I). In the center of this partition b is secured a conically-shaped chamber, D, open at its lower end, where it is joined to a cylindrical rim projecting a short distance below the partition. Within this opening are placed the gas-burners g, of which there may be one or more. Surrounding the upper part of. the chamber D, and placed concentrically with the same, so as to leave a space, H, between the two, is a casing, a, having an opening at the top for the escape of the heated air. The space between the casing to and chamber D contains layers or rings of wire-gauze, for the purpose of absorbing the heat and imparting it to the air as it passes through the space H. Instead of wire-gauze the said space may be filled with other suitable radiating material.

Gr in Figs. 1 and 2 represents a flattened spout or chamber, open at the upper and lower ends and for a short distance in front at its lower end, and made of tapering form upward, its upper end entering the chamber D.

The object of this spout or chamber is to admit of gas-burners 9 being introduced in the lower part of the stove, so that the light may be seen, and also to assist in the radiation of the heated air; or the chamber may be used, if found necessary, to convey atmospheric air into the cone D to secure a more perfect combustion of the gas in the said cone, the lower burners in that case not being used.

The heated air escapes from the opening in the upper part of the chamber into the room.

The top of the casing to is represented as being on a level with the upper surface of the chamber B. Both the conical chamber D and the surrounding casing to may, however, be extended any convenient distance above the chamber B, if desirable.

Instead of the conically-shaped chamber an arched chamber may be used, with a corresponding casin g and inclosed chamber extending from one side of the casing A to the other, and provided with a suitable opening for the escape of the heated air.

Above the chamber 13 is a chamber, F, which may serve as a mantel, and is represented as of a rectangular form, having two side pieces, f 7", extending down each side to the floor. This chamber may be of any other form desired, if not used as a mantel.

Into the chamber F is inserted the pipe 0, which conducts off the products of combustion, and in the chamber is arranged a partition, so as to cause the said products of combustion to take a circuitous course in their passage out, and thus increase the radiation of the heat. Instead of a single division-plate, as shown, several of the same maybe used, placed alternately on the upper and lower inner sides of the chamber F, and extending transversely across the same.

The arrangement of the upper gas-burners within the mouth of the conical chamber B causes a great radiation of the heat downward, which is thrown out of the opening in front of the casin This I consider of especialimportance and advantage in the arrangement and construction of my stove, as the heat is given out Where most needed-in the lower or coldest part of the room.

Gold or fresh air is supplied to the air-heating chamber B by means of a tube, E, (shown in Fig. 3 and in dotted lines in Fig. 1.)

Pipes 0 a may also be arranged to introduce air into the said chamber from the apartment itself.

The tapering chamber Gr may be made rcmovable, if desirable, so as to use only the upper burners.

The escape-pipe 0, for carrying off the products of: combustion, communicates with the chamber D at a point above the level of the burner, and, passing around the said chamber and out at the rear of the stove, enters the chamber F, where it passes to the chimney or out-of-doors.

On the inner side of the casing A or main chamber of the store may be placed radiatingplates of any suitable material to form'a heatradiatii'ig surface.

It will thus be seen that the advantages of a heat-radiating and air-heating stove are combined in my invention, the heat being radiated directly from the front and sides of the stove, while pure heated air mayv at the same time be supplied to the apartment from the upper part or sides of the stove.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination of the air-heating chamber B with the chamber D, the concentric casing a, and interposed radiating material, substantially as and for the purpose specified.

2. The combination of the tapering chamber G with the chamber D, substantially as and for the purpose specified.

3. The combination of the air-heating chamber B, the escape-pipe 0, and the partitioned mantel or radiating-chamber F, as and for the purpose set forth.

'4. The arrangement of the upper burners, g, with the chamber D, in combination with the chamber B and space H, as and for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
